Abstract (en)
The present invention discloses a calculation method and a measuring system for a cumulative dust exposure amount of respiration dust of a mine operator. A distribution law of respiration dust concentration of an operating surface is obtained based on an respiration dust concentration sensor on-site and a wind flow distribution law, a space-time trajectory of the operator is obtained according to a mine personnel positioning system, and a prediction model of an individual dust exposure amount of respiration dust is established based on a multilevel accumulative mathematical model. The prediction model is corrected with a multiple-point correction by using a single individual respiration dust detection device, and is optimized by using multiple individual respiration dust detection devices to finally obtain a calculation model for the cumulative dust exposure amount of respiration dust of the mine operator. The present invention provides a real-time and online continuous obtaining method for dust exposure amounts of respiration dust of the mine operators in underground coal dust operating places, which lays a foundation for the early warning of pneumoconiosis of the mine operators and archives management of the cumulative dust exposure amount of the operators of enterprises.
